Hand carved wooden propeller with resin boss. The propeller is made up of veneers of maple and pear and these are very delicate and look excellently to scale. The balance is excellent as is the shape. The center hub with eight bolts were modelled in 3D and casted specially for this propeller. The propeller diameter 86 mm is matches the kit part from Wingnut Wings. It has a beautiful satin lacquer finish and is super smooth to the touch.
